The time synchronization interval can be set from 1 to 10080 minutes, and the default value is 60
minutes. If the DVR is connected to a public network, you should use a NTP server that has a time
synchronization function, such as the server at the National Time Center (IP Address: 210.72.145.44).
If the DVR is set in a more customized network, NTP software can be used to establish a NTP server
used for time synchronization.
11.2.5 Configuring NAT
Purpose
Universal Plug and Play (UPnP™) can permit the device seamlessly discover the presence of other
network devices on the network and establish functional network services for data sharing,
communications, etc. You can use the UPnP™ function to enable the fast connection of the device
to the WAN via a router without port mapping.
Before you start
If you want to enable the UPnP™ function of the device, you must enable the UPnP™ function of
the router to which your device is connected. When the network working mode of the device is set
as multi-address, the Default Route of the device should be in the same network segment as that of
the LAN IP address of the router.
